FOR EYERYONE: This really is a great tutorial on light

just to re-iterate from the last post...

http://www.itchy-animation.co.uk/light.htm

Lots of great explanations... I couldn't do it any better.

He does 'dis' the 3 point light setup a little,

(but I think it is the best/simplest way to start CG lighting)

Otherwise this is a great tutorial, read all four sections.
